    Brine shrimp: all about cysts and hatching

    What are brine shrimp? The non-scientific short answer: brine shrimp are fish food that will drive your reef fish crazy.

    Rotifer Culturing at Home: Continuous Culture Set-Up and Protocol Growing rotifers as a continuous culture is easy to do, but requires a small amount of work, almost every day.

It is the content of their guts (the food they eat) that provides nutrition.  As…
